# Installing RNode Firmware on Supported Devices
|
|
|
|
Do you have one of the devices available that the RNode Firmware supports? In that case, it is very easy to turn it into a working RNode by using the `rnodeconf` autoinstaller.
|
|
|
|
With the firmware installed, you can use your newly created RNode as:
|
|
|
|
- A [LoRa interface for Reticulum](https://markqvist.github.io/Reticulum/manual/interfaces.html#rnode-lora-interface)
|
|
- A LoRa packet sniffer with [LoRaMon](https://unsigned.io/loramon/)
|
|
- A Linux network interface using the [tncattach program](https://unsigned.io/tncattach/)
|
|
- A LoRa-based TNC for almost any amateur radio packet application
|
|
|
|
So let's get started! You will need either a **LilyGO T-Beam v1.1**, a **LilyGO LoRa32 v2.0**, a **LilyGO LoRa32 v2.1** or a **Heltec LoRa32 v2** device. More supported devices are added regularly, so it might be useful to check the latest [list of supported devices](https://unsigned.io/rnode_firmware/#supported-hardware) as well.
|
|
|
|
It is currently recommended to use one of the following devices: A **LilyGO LoRa32 v2.1** (also known as **TTGO T3 v1.6.1**) or a **LilyGO T-Beam v1.1**.

## Device Variations
|
|
|
|
Some devices come with transceiver chips that are currently unsupported by the RNode Firmware. Currently devices with an **SX1276** or **SX1278** chip are supported. Support for **SX1262**, **SX1268** and **SX1280** is being added. Please support the development with [donations]({ASSET_PATH}donate.html), if you would like to see these chips supported.
|
|
|
|
> **Beware!** Some devices, like the T-Beam, use SiLabs USB chips. These may need [additional drivers](https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers) to work well on macOS and Windows. Linux usually has up-to-date drivers pre-installed. The SiLabs driver may also experience conflicts with earlier, pre-installed versions of the driver, causing a *resource busy* error, which can be fixed by [removing the old driver](https://community.platformio.org/t/mac-usb-port-detected-but-won-t-upload/20663/2).
|
|
|
|
## Preparations
|
|
|
|
To get started, you will need to download at least version 2.1.0 of the [RNode Configuration Utility](https://unsigned.io/rnodeconf). The easiest way by far is to simply install it with `pip`, if you already have that installed on your system (if not, go install `python` and `python-pip` now, it will come in handy later).
|
|
|
|
The `rnodeconf` program is part of the `rns` package. To install it, open up a terminal and type:
|
|
|
|
```
|
|
pip install rns
|
|
```
|
|
|
|
After a few seconds, you should have `rnodeconf` installed and ready to go. If this is the very first time you install something with `pip`, you might need to close your terminal and open it again (or in some cases even reboot your computer), for the `rnodeconf` command to become available.
|
|
|
|
We are now ready to start installing the firmware. To install the RNode firmware on your devices, run the RNode autoinstaller using this command:
|
|
|
|
## Install The Firmware
|
|
|
|
```txt
|
|
rnodeconf --autoinstall
|
|
```
|
|
|
|
The installer will now ask you to insert the device you want to set up, scan for connected serial ports, and ask you a number of questions regarding the device. When it has the information it needs, it will install the correct firmware and configure the necessary parameters in the device EEPROM for it to function properly.
|
|
|
|
If the install goes well, you will be greated with a success message telling you that your device is now ready.
|
|
|
|
## Verify Installation
|
|
To confirm everything is OK, you can query the device info with:
|
|
|
|
```txt
|
|
rnodeconf --info /dev/ttyUSB0
|
|
```
|
|
|
|
Remember to replace `/dev/ttyUSB0` with the actual port the installer used in the previous step. You should now see `rnodeconf` connect to your device and show something like this:
|
|
|
|
```txt
|
|
[20:11:22] Opening serial port /dev/ttyUSB0...
|
|
[20:11:25] Device connected
|
|
[20:11:25] Current firmware version: 1.26
|
|

|
[20:11:25] Device info:

|
|
[20:11:25] Device mode : Normal (host-controlled)
|
|
```
|
|
|
|
On the hardware side, you should see the status LED flashing briefly approximately every 2 seconds. If all of the above checks out, congratulations! Your RNode is now ready to use. If your device has a display, it should also come alive and show you various information related to the device state.
|
|
|
|
If you want to use it with [Reticulum](https://reticulum.network), [Nomad Network](https://unsigned.io/nomadnet), [LoRaMon](https://unsigned.io/loramon), or other such applications, leave it in the default `Normal (host-controlled)` mode.
|
|
|
|
If you want to use it with legacy amateur radio applications that work with KISS TNCs, you should [set it up in TNC mode](https://unsigned.io/using-an-rnode-with-amateur-radio-software/).

|
## External Display & LEDs
|
|
If you are using a **T-Beam** device, you can connect an external **SSD1306** OLED display using the following setup:
|
|
|
|
- The **SSD1306**-based display must be set to use **I2C** and address `0x3D`
|
|
- Connect display **GND** to T-Beam **GND**
|
|
- Connect display **Vin** to suitable power-supplying pin on the T-Beam
|
|
- Connect display **RST** to T-Beam **Pin 13**
|
|
- Connect display **I2C CLK** to T-Beam **SCL** / **Pin 22**
|
|
- Connect display **I2C DATA** to T-Beam **SDA** / **Pin 21**
|
|
|
|
On **T-Beam** devices, you can also connect external RX/TX LEDs to **Pin 2** and **Pin 4**.
